FREDERICK YEISER, OF DANVILLE, KENTUCKY.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 339,509, dated April 6,

Application filed August .21, 1885.

To all whom it may concern:

Be it known that I, FREDERICK YEISER, a citizen of the United States, residing at Danville, in the county of Boyle and State of Kentucky, have invented a new and useful Improvement in Car- Couplings, of which the following is a description.

This invention relates to that class of carcouplings which are intended to hold up the common link in position to enter the opposite draw head to couple automatically on the The object of this invention is to hold a link in one draw-head at any required angle of elevation or depression, in order that it may enter a higher or lower draw-head, and to throw the holder out of position as soon as the service is accomplished.

To this end my invention consists in the construction of a linksupporter, and in its combination with a common draw-head for a car, forming a carcoupling, as hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my invention, showing the link held at different angles of elevation. Fig. 2 is a side elevation showing the movements of the link-supporter. Fig. 3 is a plan view of the same, and Fig. 4 shows a modification of the invention.

A represents a draw-head of any usual form, adapted to receive a common link, B, and pin 0. To adapt such a draw-head for the application of my invention, it is only necessary to insert two pins, 1) b, in each side thereof, the front pin, b, being above the rear one, I), at about forty-five degrees rise therefrom. When the draw-heads are originally designed for my invention, these pins may be wrought-iron or steel bars laid in the sand, and the iron of the draw-head may be cast upon them; or they may be mere cast projections on the sides of the draw-head, or be in any other usual way formed.

1) represents my link supporter. It consists of a cross bar, a, provided with two nearly-parallel arms, 6. The bar a is to support the link B when properly set. The sides 8 are slotted at f g, to receive and rest upon the four pins 1) b b 1), two of which project at each side of the draw-head.

Serial No. 175,001. (No model.)

7 When the support is in the position shown in Fig. 1, it will restsomewhat horlzontally upon the pins, and will support the free end of the link laid on the crossbar a. The slots f g are intentionally curved parallel in order that the support may rise as it extends forward and fall as it recedes. By this means the support may be set to hold the link in line to enter an approaching draw head whether the latter be higher or lower than the one holding the link.

It is a. notch in f, whereby the distance between the outer borders of the two slots is sufficiently extended to permit the support to turn,when atthis point, upon the pins, thereby attaining a vertical or hanging posit-ion. This notch be ng at the forward end of the slot 1), the operation will be as follows:

The approaching draw-head first receives the projecting end of the link supported on the cross-bar a. Then the said cross-bar, being met by the approaching head, will be pushed back until the notch it reaches the pin 1). Now, if there were no pressure to hold up the support by friction, it would drop by gravity to a hanging position but the pushing-head would hold it. I have therefore arranged the slots relatively to the pins so that the upper slot shall strike the pin b at the same time that the notch is opposite to the pin b, and I have shaped the support with its projecting cross-bar a considerably below the slotf, so that the advancing head first pushes the support backward until the notch arrives at pin Z and the end of slot g arrives at pm I); then the continued motion of the head pushing the support backward also turns it downward on the pin 1) as a pivot, until the heads come together, when the support, already in nearly a vertical position, swings the rest of the way down freely. Now, the support, being out of service, is hung out of the way and out of danger.

The modification shown in Fig. 4 consists i dispensing with one slot and one pin, and i shaping the remaining pin to a somewhat square form to fit the sides of the slot, so th t, the support cannot revolve on the pin except at the notch, whether the support be in a horizontal or vertical position. The notch inthe border of the lower slot,

creases the slot to a width permitting the support to turn around the corners of the pin.

The two pins, when used, really represent one pair of diagonal corners of a square, and for the purpose of a generic claim I will use the words diagonal guide to represent either a single square pin or a pair of pins standing as the pins 1) I) do, as hereinbefore described.

Vhat I claim as my invention, and desire to I secure by Letters Patent, is

1 The combination of a car drawhead having a guide-pin, as hereinbefore described, projecting from its two sides, and a car-link support consisting of a cross-bar provided at each end with an arm slotted to engage the said guide-pins, the slots being enlarged at their forward ends, substantially as shown and described.

The combination of a car draw-head having a guide-pin, hereinbefore described, projecting from its two sides, and a car-link support consisting of a cross-bar provided at each end with an arm slotted to engage the said guide-pins, the slots being enlarged at their forward ends, and the main body of the slots located above the said cross-bar when in a
